Rubber ya Nitrile ikorwa na emulsion polymerisation ya butadiene na acrylonitrile.Rubber ya Nitrile ikorwa ahanini nubushyuhe bwo hasi bwa emulion polymerisation.Ifite amavuta meza cyane, irwanya kwambara cyane, irwanya ubushyuhe bwiza hamwe no gukomera..Ingaruka zayo ni ubukonje buke buke, ubukana bwa ozone, imashanyarazi mibi, hamwe na elastique nkeya.Rubber ya Nitrile ikoreshwa cyane mugukora ibicuruzwa byangiza amavuta.1) Intangiriro Yitwa kandi NBR.Rubber ya syntetique ikorwa na copolymerisation ya butadiene na acrylonitrile.Ni reberi ya sintetike ifite amavuta meza (cyane cyane amavuta ya alkane) hamwe no gusaza.Hariho ubwoko butanu bwibintu bya acrylonitrile (%) muri reberi ya nitrile: 42-46, 36-41, 31-35, 25-30, na 18-24.Nibintu byinshi bya acrylonitrile, nibyiza birwanya amavuta, ariko kurwanya ubukonje bizagabanuka uko bikwiye.Irashobora gukoreshwa igihe kirekire mu kirere kuri 120 ° C cyangwa mu mavuta kuri 150 ° C.Mubyongeyeho, ifite kandi imbaraga zo kurwanya amazi, gukomera kwumwuka no gukora neza.Byakoreshejwe cyane mugukora ibicuruzwa bitandukanye birwanya amavuta, gasketi zitandukanye zidashobora kwihanganira amavuta, gasketi, amaboko, gupakira byoroshye, ingofero yoroshye, gucapa no gusiga irangi rya reberi, ibikoresho bya reberi, nibindi, kandi biba ingenzi mubikorwa nkinganda nkimodoka. , indege, peteroli, no gukoporora ibintu byoroshye.
1. Imikorere ya Nitrile reberi nayo yitwa butadiene-acrylonitrile reberi, yitwa NBR, ifite uburemere bwa molekile ingana na 700.000.Hanze-yera kugeza yoroheje yumuhondo nini cyangwa ifu ikomeye, ugereranije 0,95-1.0.Rubber ya Nitrile ifite imbaraga zo guhangana n’amavuta, iyakabiri nyuma ya reberi ya polysulfide na reberi ya fluor, kandi ifite imbaraga zo kwihanganira kwambara no gukomera kwumwuka.Ingaruka ya reberi ya nitrile ni uko idashobora guhangana na ozone na aromatic, hydrocarbone ya halogene, ketone hamwe na solge ya ester, bityo ntibikwiriye kubika ibikoresho.Kurwanya ubushyuhe nibyiza kuruta styrene-butadiene reberi na neoprene, kandi irashobora gukora kuri 120 ° C igihe kirekire.Umuyaga mwinshi ni uwakabiri nyuma ya butyl rubber.Imikorere ya reberi ya nitrile ihindurwa nibiri muri acrylonitrile.Mugihe ibirimo acrylonitrile byiyongera, imbaraga zikaze, kurwanya ubushyuhe, kurwanya amavuta, ubukana bwumwuka no gukomera biriyongera, ariko ubukana nubukonje buragabanuka.Rubber ya Nitrile ifite ubushobozi buke bwa ozone hamwe nubushakashatsi bwamashanyarazi, ariko birwanya amazi meza.
2 Ibyingenzi bikoresha Nitrile reberi ikoreshwa cyane mugukora ibicuruzwa birwanya amavuta, nk'imiyoboro irwanya amavuta, kasete, diaphragms ya rubber hamwe n’imifuka minini y’amavuta, nibindi. Bikunze gukoreshwa mugukora ibicuruzwa bitandukanye birwanya amavuta, nka O- impeta, kashe ya peteroli, ibikombe byuruhu, diaphragms, valve, inzogera, reberi, kashe, ifuro, nibindi, nabyo bikoreshwa mugukora amabati n'ibice bidashobora kwambara.
3 Inama zogutezimbere imikorere ya nitrile rubber Kurwanya amavuta: Mugukomeza ibirimo acrylonitrile, amavuta yayo arashobora kunozwa, ariko ubukonje bukagabanuka bikurikije.Irashobora gukoreshwa igihe kirekire mu kirere kuri 120 ° C cyangwa mu mavuta kuri 150 ° C.Mubyongeyeho, ifite kandi imbaraga zo kurwanya amazi, gukomera kwumwuka no gukora neza.Byakoreshejwe cyane mugukora ibicuruzwa bitandukanye birwanya amavuta, gasketi zitandukanye zidashobora kwihanganira amavuta, gasketi, amaboko, gupakira byoroshye, ingofero yoroshye, gucapa no gusiga irangi rya reberi, ibikoresho bya reberi, nibindi, kandi biba ingenzi mubikorwa nkinganda nkimodoka. , indege, peteroli, no gukoporora ibintu byoroshye.Kunoza ubukonje no kurwanya ubushyuhe buke: reberi ya Nitrile ifite ubukana buke, kandi ubukonje bwayo bukomera hamwe no kwiyongera kwa acrylonitrile.Ukoresheje reberi ya nitrile irimo ibintu bitandukanye bya acrylonitrile no guhindura uburyo bwo guhuza imiti itandukanye yo kurwanya gusaza, ibikoresho byongera imbaraga hamwe na plasitike, amata ya nitrile yihanganira ubukonje hamwe na peteroli nziza kandi irwanya umunaniro urashobora kuboneka.
